This invention relates to improvements in admission anduse registering devices for enclosures.

The principal object of this invention is to provide means for giving authorized persons access to an enclosure and for registering the use of the enclosure by the authorized person.

A further object of the invention is to provide a unit in which equipment may be stored, access to said equipment establishing electrical circuits to illuminate the enclosure and to automatically register the accumulative hours the person may use the enclosure and the accumulative hours of all individual users.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a diagrammatic illustration of an enclosure, the walls being shown in cross section and having my invention applied thereto;

Fig. 2 is a fragmentary cross sectional view on an enlarged scale taken on the line 22 of Fig. 1;

Fig. 3 is a schematic wiring diagram;

Fig. 4 is a fragmentary front elevation of the control unit;

Fig. 5 is an enlarged fragmentary cross sectional view taken on the line 5-5 of Fig. 4; and

Fig. 6 is an enlarged fragmentary cross sectional View taken on the line 6-6 of Fig. 5.

In apartment houses and such buildings, the playing of a piano or other musical instrument is often objected to by some occupants of the building. I have, therefore, devised a soundproof enclosure which may be used by any of the tenants by paying a nominal fee based upon the hours of use. Access to the enclosure or room can only be gained by a person having a key, the actuation of which key first permits access to the room, and then the second application of the key gives access to a locker, the opening of which automatically illuminates the room, turns on a ventilating system, starts a registering meter, and maintains a pilot light, the purpose of which will be later seen.

The room may be constructed of unit sections so that the same may be readily set up in any convenient place.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred em bodiment of my invention, the numeral 5 designates wall sections which, when placed in proper alignment, form a soundproof room A, having an entrance door 4. Positioned adjacent this door is a unit B which has a jamb section 3 against which a door 6 abuts. The door 4 and the door 6 form a vestibule 2 outside the room proper. The unit B thus has one face in the room and one face in the vestibule.

On the face of the cabinet in the vestibule there isprovided a plurality of tiers of switches 8, access to which is gained by removing a padlock 9 and opening the, door 1 controlled by the pad.- lock. An electromagnetic lock is mounted in the jamb 3 the operation of which will be later described.

The face of the unitB that is within the room is divided into a plurality of hinged locker doors 13, which give access to the lockers 14 when the padlocks l5 controlling the doors are removed. Mounted adjacent each locker is a registering clock 16, one of which is shown in Fig. 4-. Within each of the lockers is a plurality ofsswitches I1, I13, and I9, which will be hereinafter referred to as door operated switches. The switch I! controls an electric circuit to energize the room. i1- luminating means, a master register, and a room ventilating means. The switch [8 controls the individual clock or recorder [6. The switch l9 controls a pilot light. These switches are operated to on position when the door I3 is opened through the medium of a push rod 2|, which is moved forwardly by a spring 22, the action of which is obvious. A time clock is shown at 23.

Referring to Fig. 3, the numeral 24 designates a time delay relay switch, and the numeral 23 a door actuated switch moved into closed position by the closing of the door 6. The fan is shown at 21, the pilot light at 28, and the room illuminating means at 29. The master register is shown at 3|.

The result of this construction is that when my unit is positioned in a room of the character described, the switches 8 will be positioned in the vestibule 2, and assuming that an authorized person has a key to one of the Padlocks 9, that person may remove the padlock 9, push the button 8 and current will flow from the positive wire through wire 36, pilot light 28, wire 46 and to time relay 24 through relay to wire 41, through button 8 to wire 48, back to negative side of the line. The current in passing from relay 24 to wire 41 will operate the magnetic lock [2, after which a person may swing the door 6 open and gain access to the interior of the room. The operator of the push button 8 will also automatically operate or set the time relay switch 24. As these types of switches are well known, it will be sufiicient to state that they may be set electrically or mechanically, and after being set have a retarding mechanism, such as clock works, dash-pot or the like to retard their return to open position. The setting or closing of the time relay completes circuit from wire 48 to wire 31 to turn on the pilot lights 29 and fan 2! and to start registers l6 and 3!. The user then removes the padlock I5 from his particular locker, swings open door [3 and thus gainsaccess to the interior of the locker where music or other material may be stored. The act of opening door I3 permits the push-rod 2! to move to its forward position, as shown. in

Fig. 5, thus actuating switches l1, I8, and I9.

The switch 19 completes the circuits as follows: Current from the wire 33 will pass through wire 34 to one side of the switch, then through switch I9, to one side of pilot light 28, thence by wire 36 to side of lines. 7

When the switch I8 is closed, current will flow from the side of this line through wire 38 to switch I8, thence by wire 39 to register 16 and to the side of line.

When the switch I! is closed, current will flow from the side of the line through wire 38, wire 4| to switch I! through switch to wire 42, thence to fan 2'! and light 29, from fan 21 and light 29 current returns by wire to door switch 26, wire 44 to the negative side of line. The master register 3| is connected to the side of the line and to the return for the fan and lights so as to only function when the lights and fan are on. The clock is bridged across line and runs at all times. The result is that the closing of the switches l1, l8, and I9 maintains the lights, the

pilot light, the fan and the register devices in operation as long as the room is in use.

Should a second person attempt to enter the room, the openingof the door 5 would break the switch 26, thus cutting oiT the lights, with the exception of the pilot light. The register would also stop so that a person would not be charged with the time they were being interrupted.

As soon as the person using the room closes the door l3, the lights in the room will be extinguished and all registering will cease.

It will thus be seen that I have provided a unit which will permit apartment house owners to secure revenue, if desired, by renting the enclosure upon a time basis in such a manner that each user automatically registers the time that the room is occupied.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim:
